When weighing other grains such as malted wheat and malted oats, don't
forget that they will differ in density.  In our discussion last February.
At that time I wrote:

Note that this agrees very well with Paul's measurement for barley malt.
Now that I know that oat malt doesn't produce a set mash, and since
commercial malt is available, I suspect that I will next try this with the
original weight ratios of malts, 3:2:8, rather than the 1:1:2 that I used
out of such a concern.
